ALINING EAR-FORWARDER FOR CORN-HUSKERS.

Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed February l, 1905. Serial No 243,656.

To all whom t may concern:

Be it known that I, CHARLES E. CURTISS, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Alining Ear-Forwarders for Corn-Huskers. of which the following' is a specification sufficiently clear and exact to enable those skilled in the art to which it appertains to make and use the same.

The invention relates to corn-Huskers, and

more especially to the means for spreading sary to illustrate the application of the invention. Fig. 2 is a side elevation of the parts shown in Fig. l. Fig. 3 is an end elevation of the alining ear-forwarder. Fig. 4 is a longitudinal sectional elevation of the parts shown in Fig. 3.

The invention is shown applied to a cornhusker of the type shown in my Patent No. 727,300, issued May 5, 1903.'

The husking-rolls A are suitably mounted in the frame B in front of and below the Snapping-rolls, (not shown,) as is common practice; but instead of being located transversely, as shown in the patent referred to, they are located longitudinally of the frame. These rolls are intergeared in the usual manner and are connected with the main driving-shaft by any suitable means. The usual shield (not Shown) is also provided to protect the drivinggearing and to conduct the ears from the snapping-rolls to the husking-rolls. All of the parts so far mentioned are substantially aS shown in the patent referred to, and hence will not need to be further described here.

Alining ear forwarders C are slidably mounted upon guides o, located intermediate of the adjacent pairs of husking-rolls and parallel with the axes thereof. At the delivery end of these rolls is a crank-shaft C', which is suitably mounted in the frame B and connected with the driving-shaft by any desired means. As herein shown this crankshaft is of the multiple form, having wrists for the ear-forwarders, which are connected thereto, respectively, by pitmen c in the usual manner. Since there is a natural tendency for the greatest number of ears to be delivered to the husker at its central portion, the middle forwarder is preferably located nearer the receiving end of the husking-rolls than those on either side thereof. By Such an arrangement the forwarders are made to operate in Zones which diverge toward the delivery end of said rolls, whereby the ears in excess of the capacity of the rolls located centrally of the husker are deiiected toward those located at the sides, thus spreading the ears uniformly over the rolls. A broken Stalk is also prevented from lying across two or more forwarders which would impede the advance of the ears, and thus interfere with the proper operation of the machine.

The alining ear-forwarders are each substantially pyramidal in form and are so located that one or more faces extend diagonally toward the delivery end of the husking-rolls. Each is provided with a body portion c2, which has a groove or way in its under side corresponding in cross-section to thatof the guide c upon which it slides. Secured to the body portion and extending laterally from one or both sides is a wing c3, which is triangular in its general outline. Its forward end extends out over the adjacent husking-roll a distance substantially equal to one-half that between the centers of adjacent pairs of rolls and provides the means for forwarding the ears. The outer edge being thus inclined laterally relative to the axes of the rolls, means are provided for deflecting the ears which lie crosswise of the rolls into alinement therewith, where they will be in proper position to be husked in the usual manner. Mounted upon each of these wings and secured thereto is a deiiector o4, the surface of which inclines di- IOO warders and are deiiected more readily to spread the ears out uniformly over the husking-rolls and to aline them therewith. These forwarders preferably are made duplex in form, having' a wing and a deector extending from each side` whereby one forwarder cooperates with two pairs of rolls. In this form the wings and dciectors preferably are made of one piece of metal, respectively, and secured together along their edges, although they may be made readily of one piece or separate pieces, as desired.

From the above it is thought that theoperation of the invention will be understood readily without further description, but, briefly stated, it is as follows: The ears'are conducted from the snapping-rolls to the receiving end of the husking-rolls in the usual manner. Such as are already in alinement with the rolls have their husls immediately engaged and torn off thereby. They are then advanced to the delivery end of the rolls by the reciprocating forwarders. which deiect the ears slightly in passing them. In case any ears lie crosswise of the rolls they are deflected into alinement therewith when they encounter the inclined edges of the wings or the inclined surfaces of the deflectors. The alining-forwarders operating in Zones which diverge from the receiving end of the rolls to the delivery end thereof, the ears in excess of the capacity of the rolls centrally located are deflected laterally until they finally iind egress from those nearer the sides of the huslier. By these means the ears are spread out evenly over all the rolls, they are detained in the husker a sufcient time to insure their being properly husked, they are alined with the rolls, so that their husks may be torn readily therefrom, and they are rapidly advanced after being hushed, whereby the operation of a machine of this class is greatly improved.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a corn-husker, the combination of two or more pairs of husking-rolls, a guide intermediate said pairs and parallel therewith, an ear-forwarder mounted above said guide and adapted to slide longitudinally thereon, and operative'means connected with said ear-forwarder.

2. In a corn-husker, the combination of two or more pairs of husking-rolls, a guide intermediate said pairs and parallel therewith, an ear-forwarder mounted above said guide and adapted to slide longitudinally thereon` said ear-forwarder having a deflector for alining the ears with said rolls, and operative means connected with said ear-forwarder.

V3. In a corn-husker, the combination of two or more pairs of husking-rolls, a guide intermediate said pairs and parallel therewith, an

ear-forwarder mounted above said guide and d adapted to slideclongitudinally thereon, said ear forwarder having laterally extending wings for alining the ears, and operative means connected with said ear-forwarder.

4. In a corn-husker, the combination of one or more pairs of husking-rolls, a guide intermediate said pairs and parallel therewith, adeflector mounted to slide longitudinally thereon, said deector having its operative surface inclined outward and rearward toward the delivery end of said rolls, and operative means connected with said deiiector.

5. In a corn-husker, the combination of a plurality of pairs of huslingerolls and a reciprocating member of substantially pyramidal form located intermediate of adjacent pairs, one or more faces of which member are inclined outward and rearward toward the delivery end of said rolls.

6. In a corn-husker, the combination of a plurality ofpairs of bushing-rolls and a plurality of reciprocating ear-forwarders located intermediate of adjacent pairs and having the central forwarder operative in advance of the others toward the receiving end of said rolls.

7. In a corn-husker, the combination of a plurality of pairs of bushing-rolls and a plurality of reciprocating ear-forwarders located intermediate of adjacent pairs, said ear-forwarders having laterally-extending wings for alining the ears, and havingjthe central forwarder operative in advance of the others toward the receiving end of said rolls.

8. In acorn-husker, the combination of a plurality of pairs of bushing-rolls, a guide between each of the adjacent pairs and an alining ear-forwarder of substantially pyramidal form slidably mounted upon said guide with its widest portion extending over the adjacent rolls.

9. In a corn-husker, the combination of a plurality of pairs of bushing-rolls and a plurality of reciprocating members of substantially pyramidal form located intermediate of adjacent pairs, and having the central member operative in advance of the others toward the receiving end of said rolls.

l0. In a corn-husker, the combination of two or more pairs of bushing-rolls, a guide intermediate said pairs and parallel therewith, an

ear-forwarder mounted above said guide and adapted to slide thereon, a crank-shaft mounted in rear of said ear-forwarder and a pitman connection therebetween.

1l. In a corn-husler, the combination of a plurality of pairs of bushing-rolls, a plurality of guides intermediate said pairs of rolls, earforwarders slidably mounted on said guides, a multiple crank-shaft mounted in rear of said forwarders and pitmen connecting said forwarders with said multiple crank-shaft.
